Embodiment 1
[0025] Depend on Figure 1 to Figure 4 As shown, a kind of anti-carbon dust backlog DC motor for a barrier gate includes a casing 1, a rotor is arranged in the casing, the rotor includes a rotating shaft 21, and an iron core 22, a commutator 3, The fan blade 4 and the commutator 3 are provided with a carbon brush assembly 7 on the circumferential side. The front and rear ends of the rotating shaft 21 are rotatably fixed to the casing 1 through bearings. The second bearing 12 at the end, the commutator 3 includes an insulating matrix 31 and a commutator piece 32, the front end of the commutator piece 32 is provided with a hook 33, the fan blade 4 is located at the rear side of the commutator 3, and the fan blade 4 includes a ring part 41 and The plurality of blades 42 located on the outer side of the ring portion, the ring portion 41 and the rotating shaft 21 are coaxially fixed, and the plurality of blades 42 are center-symmetrically arranged around the axis of the rotating sh...
Embodiment 2
[0032] Depend on Figure 5 , Figure 6 and Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that: the fan blade 4 and the insulating base 31 of the commutator 3 are integrally formed, and the ring part 41 is integrally formed on the back side of the rear end surface of the insulating base 31, so that the blade 42 is positioned at the commutator. To the rear side of sheet 32.
[0033] The commutator 3 includes an insulating matrix 31 and a commutator segment 32. The commutator segment 32 includes a commutator segment body 321 and a fixing part 322 that goes deep into the insulating matrix 31 to be fixed with the insulating matrix 31. The commutator segment body 321 is located on the insulating matrix 31. A hook portion 33 is provided on the circumferential outer side and at the front end of the commutator segment body 321 .
[0034] The fan blade 4 includes a ring part 41 and a plurality of blades 42 located on the circumferential outer side of ...
